I COMBINED DOVETAIL AND BUFFER 0R CUSHIONING- DEVICE FOR THE DOORS OF MOTOR-CARS AND OTHER VEHICLES. i

Specification of Letters Patent. Patented Ap 13, 1920 App1ication filed January 29, 1920. Serial No. 354,856.

To all whom it may concern:

Be it known that I, ARTHUR SAM CHES- TON, subject of the King of Great Britain,

holder secured to the edge of the door and adapted to engage within a recessed shoe fixed to the door-frame, or vice versa, so that the arms or branches are closed toward one another and the rubber buffer compressed between them.

According to the present invention, the

rubber cushion is inclosed within a resilient casing comprising a substantially wedge-" shaped peripheral portion and having an open front and a closed back, which latter is split longitudinally from the outer end to the peripheral portion at the inner or forward end, which constitutes the hinge about which the upper and lower halves of the cas: ing can turnrelatively to one another, and the said back of the casing is adapted to be secured 'to the door-frame or the like so as not to interfere with the said relative angular movement of the two parts of the casin Figure l of the accompanying drawings represents a rear elevation of the buffer device, showing the same engaged with and compressed by the shoe which is fixed to the door-frame.

Fig. 2 is a similar view, but with the bui.

fer disengaged from the shoe.

ig. 3 is a horizontal section and Fig. i is a verticai section, showing. how the device is secured to the door.

Fig.5 shows the component parts separately.

The improved buiier or cushioning device consists of a substantially wedge-shaped block of rubber a inclosed within a similarly shaped sheetsteel casing b which is open the front, but is gapped or divided longitudinally at 6 along the opposite side and across the wider end, so that the upper and lower halves are connected hinge-wise only at the forward endby the peripheral part of the casing, as at 6 this peripheral part belng of a resilient nature so as to allow of the two said halves of the casing being pressed together in order to compress the rubber between them. The device is fixed to the edge. of the door by a screw 0 passed through a metal bush d fitted in the outer uncovered face of the rubber, and also by screws f passed through holes e, c in the back or closed side of the casing, the hole e in the one half of the latter being elongated in the form of a slot to allow of the relative move ment of the two halves when compressing the rubber.

When the door is closed, theabove-described dovetail and bufier device is adapted to engage within a recessed shoe or plate g let into the edge of the door frame, the front portion of the recess being narrower than the wider end of the wedge-shaped bufier, so as thereby to press the two halves of the metal casing together and thus compress the rubber block between them, as in Fig. 1, thereby allowing the door a very slight movement corresponding to the stress of traveling on the road, and obviating the necessity of fastening the door by fixed dovetails (with the attendant result of either forcing the'pillars out of position orinjuring the framing ofthe door) but at the same time positively obviating any chattering of the door on to the pillars.

.Ha'ving fully described my invention, what I claim and desire to secure by Letters Patent is 1. A combined dovetail and buffer device comprising a rubber cushion in'closed within a resilient casing consisting of a substantially wedge-shaped peripheral portion having an open front and a closed back, which le split longitudinail. fl
